MG Im5 vs Kia Rio

What's the difference?

The MG IM5 Performance is fast, comfortable, quiet and super refined. Putting some minor spec and active safety niggles to one side, it offers the features, tech and price to match it with its well-credentialled and already popular mid-size EV sedan competitors. Is there room for one more? We think there should be.

The Rio S Manual is a fun-to-drive little car with a big practicality and multimedia offering in a segment rapidly heading towards extinction.

While some elements of the drive experience are reminiscent of budget cars from 10-20 years ago, Kia makes up for it by wrapping the Rio in a contemporary looking and feeling package, ready for the buyer who needs no frills and demands no nonsense. Until the manual transmission goes the way of the dodo, there is almost no better option.

Playing spot the straight line on the outside of the MG IM5 is like an automotive design version of Where’s Wally? There aren’t many, in the midst of an unrelentingly curvaceous exterior treatment.

At close to five metres long and two metres wide the IM5 is appreciably longer (+211mm), a little wider (+27mm) and a bit taller (+33mm) than a Tesla Model 3. Think BMW 5 Series in terms of overall size.

And the soft-form shape is functional; the swoopy liftback boasting an ultra-slick 0.24 drag coefficient.

That said, I’m not convinced by the ‘Periscopic’ cameras informing the driver assistance systems from the front guards. They scream tacked-on afterthought. But a touch-only initial opening function for the flush door handles is cool and makes life easier.

The curves continue inside with soft-padded surfaces around the dash and doors, but the straight edge obviously came out for the 10.5-inch central media screen and vast 26.3-inch upper display. There are next to no buttons; even exterior mirror adjustment is directed from the screen to a multi-function steering wheel control.

System software (powered by a Qualcomm ‘Snapdragon’ chip) is lightning fast with a two-finger up and down swipe shortcut function on the central screen for ventilation and other functions.

The interior is light and bright thanks to the enormous panoramic sunroof. It’s been fine in cooler winter conditions during this test but it could be interesting to revisit in the heat of an Aussie summer

There are two interior colour schemes available - the ‘Highland Grey’ of our test car or ‘Dover Beige’ for those brave enough to live life with the threat of scuff marks on your shiny new car’s glamorous but vulnerably light interior.

While notable equipment is missing, the Rio reclaims lost ground with the way it looks, and to a degree, the way it feels.

Ever since this new generation hatch launched, I’ve thought it brings a slick modern design to the city-car space, and even in its most rudimentary form as-tested (our car even came in the most basic ‘Clear White’ paint) it’s a great looking little hatch.

Sure, it doesn’t have the romance factor of the Fiat 500, nor the more delicate curvature of the much more expensive new-generation Toyota Yaris, but it certainly has a more refined visage than, say, the MG3 whilst feeling a bit more grown-up than the Suzuki Swift.

Solid, squared-off lines give this car a sporty pose, and its frowny-face and blocky rear round out a stout city-car persona, and I especially like the way even this most basic trim is adorned with contrast pieces, a spoiler above the boot lid, and body-coloured door handles and mirrors.

Sure, the 15-inch steelies dress it down a bit, but on the Rio these leave the impression of financial prudence rather than cost-cutting.

Inside is basic but tidy. The overall look maintains a hint of sportiness, with an appealing symmetrical finish to the dash.

There’s no question the Rio is a budget model when it comes to the touch though, with everything either a soft polyurethane or a nasty hard plastic, so while it all might look neat it’s far from the most comfortable place to be for long periods of time.

The basic dot-matrix multifunction display, chunky plastic air-conditioning controls, and polyurethane items from the wheel to the handbrake and shifter are reminders of a bygone era, but the overall aesthetic of the driver’s space is pleasing.

There’s plenty of breathing room up front and in terms of storage one of the first things worth calling out are the long but relatively narrow door bins. No good for anything above unusually slender bottles, even if they’re lying down.

No conventional glove box in the dash, but there is a large lidded box (cooled and heated) between the seats that doubles as a centre armrest. It’s supplemented by a big stowage area underneath the flying buttress style centre console.  

There are two cupholders in the centre console as well as a wireless device charging pad in front of them with a vaguely phone-shaped oddments bin alongside it.  

Move to the rear and the IM5’s 75mm wheelbase advantage over the Tesla Model 3 is clear. Heaps of knee and headroom for me at 183cm sitting behind the driver’s seat set to my position. 

But… the seat sits low which pushes your knees up into the air to the point where my thighs are not contacting the seat cushion. Even though the rear seat reclines to a certain degree it’s a problem compounded by a chronic lack of room for your toes under the front seat. Awkward.

There are map pockets in the front seatbacks, modest bins in the doors and a fold-down centre armrest with two cupholders. Adjustable ventilation in the rear of the front centre console always makes life in the rear seat more pleasant.

The car also houses ‘Strong Magnets’ at various points around the cabin and boot, with a configurable adapter able to lock a phone or tablet into place for the entertainment of, in our case, back seaters. 

Speaking of devices for entertainment, there are two USB-C sockets and a 12-volt outlet in the front and another USB-C and 12V in the back, so charging isn’t an issue. 

The IM5 is a liftback so the boot aperture is generous and a capacity of 457 litres with the rear seats up is decent for a car of this size, although that’s less than the Tesla Model 3 (594L) which has an additional well under the floor. 

Still, enough room for the largest (124L) and smallest (36L) suitcases from the CarsGuide three-piece luggage set with some room to spare.

The power tailgate can be operated hands-free via the key or an always welcome under bumper kick function.

Volume expands to 1290 litres with the rear seats folded and there’s a modest 18-litre ‘frunk’ under the bonnet.

The bad news is a repair-inflator kit rather than a physical spare wheel, but the better news is the IM5 Performance can tow a 1500kg braked trailer (750kg unbraked).

The IM range also features the ‘MG iSmart’ app allowing remote control of various functions including charging, checking vehicle location and route planning. 

I'd argue the key reason to buy the Rio at this end of the market is that it has the most space and largest cabin relative to its rivals, bar maybe the Suzuki Baleno.

All-round practicality is great, with front passengers scoring a low, sporty seating position with a high roof, and so much width in the cabin it almost feels like the Rio belongs in the next segment up.

Storage options up front include a large bottle holder and bin in each of the doors, dual cupholders next to the handbrake up front, and a large storage tray underneath the climate unit. Unlike the Yaris or Mazda2, the Rio features a small armrest console box, which gives a small lift to the ambiance of the cabin.

Back seat passengers are treated to great space for this segment, which feels nice and open courtesy of the large rear windows. At 182cm tall, I have airspace for my knees behind my own driving position, as well as relatively healthy headroom and ample width, which is again more like a car in the next segment up.

Rear passengers don’t get adjustable air vents, but there is a single USB port, a single pocket on the back of the passenger seat, and small bottle holders in each of the doors.

Perhaps the Rio’s biggest drawcard is its boot capacity, which at 325 litres is one of the largest in the city car class. Unlike the Yaris, Mazda2, or Suzuki Swift, the Rio will actually accept the CarsGuide three-piece luggage set with the rear seats up, although the rear view was obscured by the medium case.

Thanks to the boxy roofline, the Rio offers a cavernous 980L with the rear seats folded down, and despite its abundance of room, maintains a space saver spare wheel under the floor.

Value seems less important here when you’re contending with a limited list of potential options at this end of the market.

The Rio S manual currently wears an MSRP of $19,690, and if you’re able to shuffle cogs yourself, it counts its rivals as the Suzuki Baleno GL ($18,490), Suzuki Ignis GL ($19,490), or Fiat 500 Lounge ($19,550).

There’s also the option of the MG3 (from $18,990) or Kia’s own much smaller Picanto (from $15,990).

I’m pleased to report the Rio S is one of the best among these options, though. Not only is this car much more modern in terms of its platform and design than pretty much anything on that list, it packs great standard equipment, too.

The major wow-factor item is the Rio’s best-in-class multimedia system, consisting of an 8.0-inch touchscreen with wireless Apple CarPlay and Android Auto connectivity, just one of the areas where this car will grab eyes over rivals.

Elsewhere is a predictably honest list of standard equipment, including basic halogen headlights, 15-inch steel wheels, manual air conditioning, cloth seat trim with a polyurethane steering wheel, a small multifunction display in the dash, two USB ports, a six-speaker audio system, and surprisingly, steering-wheel mounted controls.

There’s no keyless entry or push-start ignition, and this level of equipment makes you feel lucky to have automatic headlights. Sadly, the S manual also misses out on the basic luxury of cruise control.

It’s cheap, missing a lot of gear, and feels it with an abundance of plastic trims, but somehow this car gets by with almost everything you really, truly need. Sure, it’s a bit of a hark back to the equipment lists of the early 2000s, but if you’re just looking for a basic car to get the job done, you could do far worse than this Kia with its impressive multimedia offering.

The MG IM5 Performance is powered by an electric motor on each axle - the rear (372kW/500Nm) more powerful than the front (200kW/300Nm), for overall outputs of 572kW (that’s close to 770hp) and 802Nm of pulling power.

The official term for that amount of grunt is… a lot. And we’ll get to what it means on the road in the Driving section shortly.

The Rio is beginning to fall behind here with an antiquated 1.4-litre four-cylinder non-turbo petrol engine. Peak outputs aren’t far off where they should be for this segment, with 74kW of power and 133Nm of torque, although they arrive at the most distant end of the rpm range (6000rpm and 4000rpm respectively) so you need to rev it.

It can be clumsy to extract this power, too, with the engine paired in this circumstance to a six-speed manual which leaves a lot to be desired in terms of action and clutch feel.

While the abundance of ratios can be beneficial for fuel consumption, it’s clear this car was designed to be paired with the more modern three-cylinder turbocharged engine only available on the top GT-Line trim.

The MG IM5 Performance features an 800-volt electrical architecture which means the 100kWh NCM battery can accept a DC peak charge of close to 400kW.

Only snag is the highest you’ll currently find in Australia is 350kW. But even at that rate you’ll still be looking at a 30-80 per cent charge in just over 15 minutes. Maximum AC charge rate is 11kW.

Claimed range is 575km (WLTP) which is less than the Tesla Model 3 Dual Motor AWD at 629km.

Over a week of city, suburban and some freeway running we saw average energy use of 20.6kWh/100km which is on the high side for an EV of this size but maybe not for one with this kind of performance potential. 

The Rio S manual has an official combined cycle fuel consumption rating of 5.6L/100km, which is about right for a light car with a small engine.

On test, covering largely urban kilometres, I saw a higher but not unreasonable 7.4L/100km. Still, this number isn’t too far off what some larger cars with 2.0-litre engines are capable of.

Rios with this engine accept entry-level 91RON unleaded fuel, and have 45-litre fuel tanks. They are only compliant with Euro 5 emissions regulations.

First things first, the IM5 Performance is supercar fast. This 2.3-tonne five-seater blazes from 0-100km/h 3.2 seconds and with its dual motors combining to produce 572kW/802Nm, eye-widening performance always resides underneath your right foot.

But it’s not all about straight line speed. Ride comfort is excellent. Underpinned by an all-new platform, the IM5’s suspension is by double wishbones at the front and multi-links at the rear. But the key to its bump and rut smoothing ability is air suspension and ‘continuous control’ active damping.

Fold in double-glazing on the full-length glass roof and side windows, as well as active noise cancellation and you have a serene interior environment at any speed. Also worth noting the front seats are great; as grippy as they are comfortable.

Not only that, despite its relative heft, this mid-sizer steers well, too. Not the last word in road feel but it points accurately and the standard rear steering helps with prompt (but never jerky) cornering turn-in. Flick to ‘Sport’ mode and the IM5 is up for some enthusiastic running.

The rear wheels can turn up to 12 degrees in the opposite direction to the fronts at slow speed, which makes for a usefully tight 10-metre turning circle. But above that, at lesser angles, it adds extra stability and decisiveness in the way the car steers through even tight, twisty sections.

Rubber is top-shelf Pirelli P Zeros on 20-inch alloys (245/40 fr - 275/35 rr) and it grips hard, especially in the wet weather over much of the test period. Braking is solid, as it needs to be, with ventilated discs all around and four-piston callipers at the front. 

No adjustable regen braking but you can feel the ‘Cooperative Regenerative Brake System’ (CRBS) doing its thing when you lift off the accelerator. 

The physical rear view is modest thanks to the slope of the back window reducing its functional area for the driver to that of a 1950s VW Beetle. Even the interior rear-view mirror is tiny and folds up into a recess in the headliner if you’d prefer life without it.

But that’s where a rear camera view popping up on the upper screen display (accessed via the right-hand steering wheel click control) comes in handy. Side camera views are also available as is a 360-degree overhead view, which makes parking straightforward.

If you need more parking help there are various self-parking modes including a nifty ‘Curbside’ function that will realign the car hands-free if you’re parallel parked too far out from the kerb.

In a similar vein, a ‘Rainy Night’ mode projects left and right rear views onto the main screen using AI to enhance clarity and highlight pedestrians and cars.

Overall the ADAS (Advanced Driver Assistance Systems) are relatively unobtrusive but we found ourselves switching off the incessant overspeed chime that sounds for 10 seconds if you creep over the indicated speed limit, even when the system has misfired on the correct speed. For example, 40km/h school zones on a Sunday.

The over-zealous driver distraction warning also occasionally issued a visual and audible slap on the wrist when I was looking straight ahead. Tellingly, there’s a specific quick screen for turning both these functions off, but it kinda defeats the purpose of having them in the first place.

We also found the adaptive cruise control to be hesitant in multi-lane environments, reducing speed occasionally because the system seemingly believed a car was set to merge, when it wasn’t.

A six-speed manual with a tiny non-turbo engine is an absolute oddity in today’s new car market, but as a result of its rudimentary approach, there’s something refreshingly honest about the Rio S.

The engine requires a wringing to extract the desired result, and a lot of action on the gears, as six speeds proves to be quite a few to work your way through before you achieve cruising speed.

As so much interaction is required with the transmission, I wish it was tighter when it comes to the clutch which feels a bit doughy at the best of times.

The Rio is very organic, though, with next to no electrical assistance for any of its interaction points offering the driver a high level of control.

The steering is direct, but as a result of a cheaper rack (with less teeth compared to this car’s Stonic relation), it feels simple and brittle when it comes to feedback.

The same criticism can be levelled at the suspension, which errs on the side of firm. This attribute combines with the low seating position to make even this most basic Rio an absolute hoot in the corners.

But it can be a little crashy over every-day potholes and corrugations, despite the abundant amount of rubber cladding the 15-inch steel wheels.

Visibility is superb out of this little car’s big windows, making you feel in control of your surroundings (necessary in the multi-lane confines and tight parking conditions of a city), and ergonomics in the cabin are absolutely on-point with the large touchscreen elements easy to reach and the instruments taking a basic no-nonsense form.

While noise levels are okay at urban speeds, they pick up above 80km/h, making the Rio more unpleasant to drive over long distances than, say, the more upmarket-feeling Yaris.

The Rio does find its place in this price bracket as a fun-to-drive, but predictably rudimentary experience, for the niche audience of drivers seeking an entry-level car who are still able to shift gears themselves.

Sadly, the Rio S misses out on any advanced active safety items. This is one area where city-sized cars are struggling to keep up, as expensive active safety systems tend to push them well into the mid-$20,000 region.

Unlike the mid-range Rio Sport, the S has no auto emergency braking, lane keep assist, or driver attention alert.

It makes do with the more basic array of brake, stability and traction controls, with the addition of a great reversing camera, three top-tether and two ISOFIX child seat mounting points, and six airbags.

The Rio carries a valid five-star ANCAP safety rating, to an earlier 2017 standard before its missing modern active safety items were mandated.

The MG IM5 Performance is covered by a seven-year/unlimited km warranty, which is a plus, but the catch is it’s conditional on authorised dealer servicing. Go elsewhere and the term drops to a more common five years/unlimited km. The drive battery is covered for eight years/160,000km, which is the norm in the Aussie market

Servicing is required every 12 months or 20,000km with charges averaging $586 per workshop visit for the first five years, which is on the high side for an EV, even at this price point, the average bumped up by a more than $1400 doozy at year four.

MG IM models are sold (with service available) through all of MG’s 100-plus dealerships across the country, so no concerns there.

The Rio again gets the edge on its budget competition with a lengthy seven-year, unlimited kilometre warranty. In this space it only butts heads with the MG3, which offers a matching promise.

Roadside assist is included for up to eight years if you continue to service with Kia, and there's also a capped price service program for the duration of the warranty, covering up to 105,000km.

The Rio needs to be serviced once every 12 months or 15,000km, and prices range from $269 and $608 per visit, for an annual average of $409.40.

Not the cheapest servicing schedule we’ve seen, particularly when compared with the likes of Toyota.
